Abstract

Although radiotherapy improves progression-free survival in early-stage HL, substantial concerns remain regarding delayed normal tissue effects impacting quality of life and survival. We hypothesized that treatment with combined-modality therapy (CMT, chemotherapy and radiotherapy) improves overall survival among 10-year survivors when compared to treatment with radiotherapy or chemotherapy alone.We compared patients in the SEER database diagnosed with stage I/II Hodgkin lymphoma between 1983 and 2006 who received chemotherapy and/or external-beam radiation and survived at least 10 years. Our primary study outcome was overall survival; we additionally analyzed cause-specific and other-cause-specific survival.Of 10,443 10-year survivors of stage I/II classical Hodgkin lymphoma, 33.6% received chemotherapy alone, 23.8% radiotherapy alone, and 42.6% CMT. Median follow-up was 16.1 years. On multivariate analysis including race, stage, gender, age, and "modern" treatment in 1995+, 10-year survivors who received CMT had improved overall survival relative to survivors who received RT alone (HR=1.41, 95% CI=1.21-1.64, p<0.01) or chemotherapy alone (HR=1.35, 95% CI=1.16-1.57, p<0.01).This survival difference was driven by an increase in death due to both HL and non-HL causes in those treated with chemotherapy alone. Our analysis suggests that CMT offers optimal survivorship for patients with stage I/II Hodgkin lymphoma.
